Overview
Acute coronary syndrome (ACS) is a broad term for three types of coronary artery disease that affect millions of people each year. These potentially life-threatening conditions occur when a blockage causes blood flow to your heart to suddenly slow or stop.
People with ACS can experience unstable angina or a heart attack (myocardial infarction). Common signs include chest pain or pressure (angina), shortness of breath (dyspnea) or dizziness.
Acute coronary syndrome is a medical emergency that requires immediate attention. Prompt treatment is important to ease symptoms and prevent complications. If you think you’re having a heart attack, take an aspirin and call 911 immediately.
